Energy identification codes

The purpose of the Energy Identification Coding (EIC) Scheme is to provide a standardised codification scheme for identification of the components of power systems (both electric power and gas) and market participants. The EIC system is established in order to facilitate data exchange processes between a power system and market participants on a national and European scale

EIC coding scheme has been established by the European Network of Transmission System Operators (ENTSO-E) upon request of the European Commission. ENTSO-E is also nominated as the EIC Central issuing authority (EIC CIO). The tasks of EIC CIO include development and supervision of code management processes, maintenance of a register of European scale, as well as nomination of the local issuing authorities (EIC LIO). EIC LIO is responsible for maintenance of the national register and organization of the national management processes (including issuing and deactivisation of codes) according to the guidelines developed by ENTSO-E.

AS “Augstsprieguma tīkls” is the nominated EIC LIO in the Latvian electric power market and AS "Conexus Baltic Grid" is the nominated EIC LIO for the Latvian gas market, but to ensure the uniqueness of "X" type EIC, starting from April 2024, AS “Augstsprieguma tīkls” issues "X" type EIC to both electricity and natural gas market participants.

The codes issued so far remain unchanged and all EIC issued by AS "Augstsprieguma tīkls" can be found on the EIC CIO website.

EIC consists of 16 characters. The first two mean the local issuing authority (the code allocated to JSC "Augstsprieguma tīkls" is 43). The third character means EIC type (see the table  “EIC types”). The fourth to 15th character is a freely allocated combination of letters and numbers and the last character is a control sign.

+ EIC types

According to the ENTSO-E guidelines the following EIC types exist:

EIC type EIC example Explanation
X 43X00PIEMERS000B EIC which is used to identify an Energy market (both electric power and gas) participant or energy consumer.
Z 43Z00PIEMERS000K EIC which is used to identify the measurement point ensuring electric power calculation. For example, electricity meter.
W 43W00PIEMERS000P EIC which is used to identify an object/equipment for the generation, consumption or storage of electricity. For example, wind turbine, hydroelectric power station turbine or their set. This EIC type may not be used in order to identify lines or transformers.
T 43T00PIEMERS000U EIC which is used to identify interconnection lines, internal lines and transformers.
A 43A00PIEMERS0000 EIC which is used to identify substation and transformer points.
V 43V00PIEMERS0002 EIC which is used to identify the physical or logic place where the IT system is located.
Y 43Y00PIEMERS000Y EIC which is used to mark a geographical or market area, for example, in XBid platform.


+ Request EIC

The participants of the Latvian Energy market (both electric power and gas) willing to obtain the energy identification code (EIC) are required to fill in the EIC request form in electronic form. AST will review the application and provide a response within one week. To get more information about EIC, send an email to [email protected].

+ The allocated EIC

The energy identification code (EIC) system is based on a fixed-length alphanumeric code. An EIC consists of 16 characters and contains information about the EIC issuing authority, as well as information about the identifiable object.
